It just lift the high frequency part coefficients we can refer the HTK book, equ 5.12 We can plot the 12 coeffs while using these condition: N=13; %N is the number of cepstral coefficients L=22; % L is the liftering parameter ceplifter = ( 1+0.5*L*sin(pi*[0:N-1]/L) ); plot(ceplifter); xlabel('number of cepstral coefficients'); ylabel('ceplifter'); ...
